Public bug reported:

[L3] stale device/process remain in network node after router removed

ENV: stable/queens
Step to reproduce:
1. create HA router
2. attach router interface to subnet
3. remove router interface from subnet
4. delete router

Just run these 4 steps a few times, you may see there will be ha-ports
and neutron-keepalived-state-change process remain in the network node
after router was totally removed.

Test script:

function create_clean_net_struct()
{

  neutron net-create scale-test-net-${1}
  subnet_id=`neutron subnet-create --name scale-test-subnet-${1} scale-test-net-${1} 192.168.${1}.0/24|grep "| id"|awk '{print $4}'`
  router_id=`neutron router-create scale-test-router-${1}|grep "| id"|awk '{print $4}'`
  neutron router-interface-add $router_id subnet=$subnet_id

  neutron router-interface-delete $router_id subnet=$subnet_id
  neutron router-delete $router_id
  neutron subnet-delete scale-test-subnet-${1}
  neutron net-delete scale-test-net-${1}
}
create_clean_net_struct $1
